Given numbers are 153,436,115,109

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 153,436,115,109 is 7671420.

Find LCM of 153,436,115,109 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

109 x 153 x 4 x 115 x 1 = 7671420

Therefore, the lowest common multiple of 153,436,115,109 is 7671420.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

153 x 436 x 115 x 109 = 836184780

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

153 : 1, 3, 9, 17, 51, 153

436 : 1, 2, 4, 109, 218, 436

115 : 1, 5, 23, 115

109 : 1, 109

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,436,115,109, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

436:2x 2x 109

115:5x 23

109:109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

109 = 109

Therefore, the value for common factors is 109.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 836184780/(1x109)

LCM = 836184780/109

LCM = 7671420

Thus, we can understand that the LCM of 153,436,115,109 is 7671420.

Here are some samples of LCM of two or more Numbers calculations.
